摘　　要： 采用生长速率法测定了芒果不同品种茎叶粗提物对芒果炭疽病菌(Colletotrichum gloeosporioides Penz)、芒果蒂腐病菌(Botryodiplodia theobromae Pat)、香蕉炭疽病菌[Colletotrichum musae(Berk&Curt)Arx]、香蕉枯萎病菌(Fusarium oxysporum f.sp.cubense)、西瓜枯萎病菌(Fusarium oxysporum f.sp.niveum)和水稻纹枯病菌(Rhizoctoniasolani Kühn)6种病原菌的抑菌活性。结果表明,在5 mg.mL-1浓度下,芒果茎叶粗提物对6种病原菌具有好的抑菌效果。其中A3、A17、A25和A65对水稻纹枯病菌的抑菌活性在60%以上,A3对芒果炭疽病菌和芒果蒂腐病菌的抑制活性分别为72.73%和61.67%,A17对芒果蒂腐病菌的抑制活性为65.83%,与苦参碱药剂间差异显著,且都优于苦参碱的抑菌活性;A3粗提物对芒果炭疽病菌的EC50为2.2457 mg.mL-1,对芒果蒂腐病菌的EC50为3.3215mg.mL-1。 The antifungal activities of the mango extracts were tested against Colletotrichum gloeosporioides,Botryodiplodia theobromae,Colletotrichum musae,Fusarium oxysporum f.sp.cubense,Fusarium oxysporum f.sp.niveum,Rhizoctonia solani by using mycelial growth rate method.The results indicated that the antifungal activities of the extracts were good against six kinds of fungal at the concentration of 5 mg·mL-1,especially the antifungal activities of the extracts from mango from A3,A17,A25,and A65 were more than 60% against Rhizoctonia solani,the antifungal activities of the extracts from mango A3 were 72.73% and 61.67% against Colletotrichum gloeosporioides and Botryodiplodia theobromae,the antifungal activities of the extracts mango from A17 was 65.83% against Botryodiplodia theobromae;the EC50 of the extracts from mango A3 was 2.2457 mg·mL-1 against Colletotrichum gloeosporioides,and was 3.3215 mg·mL-1 against Botryodiplodia theobromae.
